Angle 1 and 2 are vertical angles. If angle one
equals 55 degrees. What does the other angie
equal?

Answer:

47/10 - 3.2

Step-by-step explanation:

Given

Dolphin = 3.2

Bird = 47/10

Required

What is the vertical distance between both

Using a vertical scale;

Represent the bird "above sea level" position with positive and dolphin at "below sea level" position with negative.

The vertical distance between them is as follows;

Distance = +[Above The Sea] - [Below The Sea]

Distance = +47/10 - 3.2

Distance = 47/10 - 3.2

Hence, the vertical distance between both is 47/10 - 3.2

(a) correct

(b) The exterior angles of a polygon add to 360°, so the other 8 interior angles add to 160°. Since an exterior angle and its corresponding interior angle add to 180°, the 8 exterior-interior angle pairs we must consider add to 1440°. Thus, the answer is 1280°.

For the linear equations provided by the coordinates in the table;

The first equation of this system is y = -2x.

The second equation of this system is y = x - 3.

The solution to the system is (1, -2).

We have four points (-5,10), (-1,2), (0,0), and (11,-22) for first equation, and four points (-8,-11), (-2,-5), (1,-2), and (7,4) the second equation.

The slope (m) is given by the formula (y2 - y1) / (x2 - x1).

For the first line, we can use the points (-5,10) and (-1,2)

m1 = (2 - 10) / (-1 - (-5)) = -8/4 = -2.

the first equation is y = -2x

the second line, we can use the points (-8,-11) and (-2,-5)

m2 = (-5 - -11) / (-2 - -8) = 6/6 = 1.

the second line has a slope of 1,

the equation should have the form y = x + c.

To find c, we can use one of the points, for instance (-2,-5):

-5 = -2 + c => c = -5 + 2 = -3.

So, the second equation is y = x - 3.

the solution to the system, we need to find where the two lines intersect.

y = -2x

y = x - 3

Setting both equation equally

-2x = x - 3

=> 3x = 3

=> x = 1.

Substituting x = 1 into the first equation

y = -2(1) = -2.

the solution to the system of linear equation would be (1, -2).

the width of the river is approximately 64.03 feet.

To determine the width of the river, we can use the concept of triangle similarity.

Let's assume that the river width is represented by the variable "x".

From the information given, we have a right triangle formed by the river, the fishing hole, and the campsite. The campsite is located 200 feet from the fishing hole, and the river width is the unknown side.

Using the Pythagorean theorem, we can set up the equation:

x^2 + 200^2 = (200 + 110)^2

Simplifying the equation:

x^2 + 40000 = 44100

x^2 = 44100 - 40000

x^2 = 4100

Taking the square root of both sides:

x = sqrt(4100)

x ≈ 64.03 feet

Therefore, the width of the river is approximately 64.03 feet.

To find the ODE that determines the family of all circles passing through the points (1,0) and (-1,0), we must first find the general equation for a circle. The equation of a circle with center (h,k) and radius r is given by:

\((x - h)^2 + (y - k)^2\)

\(= r^2\)

If a circle passes through the points (1,0) and (-1,0), then its center lies on the perpendicular bisector of the segment joining these two points.

The perpendicular bisector is the line x = 0.

Hence, the center of the circle lies on the line x = 0.

The distance between the center of the circle and the point (1,0) is equal to the distance between the center and the point (-1,0). This is because both of these points lie on the circle.

Hence, the center of the circle lies on the line x = 0 and has the form (0,y).

Let the radius of the circle be r. Then, we have:

\((1 - 0)^2 + (0 - y)^2 \\= r^2 and (-1 - 0)^2 + (0 - y)^2 \\= r^2\)

Simplifying these equations, we get:

\(y^2 + 1 = r^2 ... (1)y^2 + 1 = r^2 ...\)

(2)Equating the right-hand sides of equations (1) and (2), we get:

Answer: True.

By definition, a stochastic matrix is a square matrix where each entry is a non-negative real number and the sum of each row is 1.

If A is a stochastic matrix and v is a vector in its 1-eigenspace, then we have:

Av = λv

where λ = 1 is the corresponding eigenvalue.

Multiplying both sides by 1/λ = 1, we get:

v = A v

This means that the vector v is also in the range of A, which is a subspace of the vector space R^n.

Since A is a stochastic matrix, the rows of A sum to 1, and therefore the columns of A also sum to 1. This implies that the vector of all 1's, which we denote by u, is also in the range of A.

Since v is a nonzero vector in the 1-eigenspace and u is a nonzero vector in the range of A, the span of v and u is a two-dimensional subspace of R^n.

Moreover, since A is a stochastic matrix, we have:

Au = u

This means that the vector u is also in the 1-eigenspace.

Therefore, the 1-eigenspace of A is a line spanned by the vector u, which is a nonzero vector in the range of A.

if a is a stochastic matrix, then its 1-eigenspace must be a line: True.


A stochastic matrix is a square matrix with non-negative entries where each row sums to one. The 1-eigenspace of a matrix is the set of all eigenvectors with eigenvalue 1.

Let v be an eigenvector of a stochastic matrix A with eigenvalue 1. Then we have Av = 1v.

Multiplying both sides by the transpose of v, we get v^T Av = v^T v.

Since A is a stochastic matrix, its columns sum to 1 and therefore, its transpose has rows that sum to 1. Thus, v^T Av = 1 and v^T v = 1.

This implies that v^T (A-I) = 0, where I is the identity matrix. Since A is stochastic, I is also stochastic and has a unique 1-eigenspace, which is a line spanned by the vector (1,1,....1)^T.

Therefore, v must be a scalar multiple of (1,1,....1)^T, which implies that the 1-eigenspace of A is a line.

Therefore, the statement "if a is a stochastic matrix, then its 1-eigenspace must be a line" is true.

To find the exact values of the trigonometric ratios of angle θ, we need more information about the triangle. Trigonometric ratios are defined based on the ratios of the sides of a right triangle. In order to calculate these ratios, we need to know the lengths of the sides of the triangle or have additional information about the angle.

Without specific values or additional information about the triangle, we cannot determine the exact values of the trigonometric ratios. Each trigonometric ratio (sine, cosine, tangent, cosecant, secant, and cotangent) requires different side lengths of the triangle to be calculated accurately.

In a linear regression model, the linearity assumption refers to the relationship between the independent variables and the dependent variable.

It assumes that the dependent variable is a linear combination of the independent variables, with the coefficients representing the effect of each independent variable on the dependent variable.

In the given model, y^2 = ax_1 + bx_2 + u, the dependent variable y is squared, which introduces a non-linearity to the model. The presence of y^2 in the equation makes the model non-linear, as it cannot be expressed as a linear combination of the independent variables.

If you want to include quadratic or cubic terms for the dependent variable y, you would need to transform the model accordingly. For example, you could use a quadratic or cubic transformation of y, such as y^2, y^3, or even log(y), and include those transformed variables in the linear regression model along with the independent variables. This would allow you to capture non-linear relationships between the dependent variable and the independent variables in the model.
